From the number of positive reviews this item has, it would appear that sometimes it works well.... depending on what bike you have and particularly the location of the gas cap. However, I can only speak from my experience using it on a Ducati 998. First of all, when the 2up bar is fitted to a 998, it is NOT possible to refuel. Which is very, very inconvenient. Secondly, the gas cap position on a 998 is relatively low, which means that the passenger has an awkward wrist angle to grip the 2up handle bar. It seems to be relatively well made, although it is heavy and expensive and it's hard to recommend to Ducati owners that own a similar bike. Bottom line is that this seems to be a great concept, but the 'universal' design means that fitment is compromised on some bikes.
